    Absolutely!

    You need to create a custom widget, and the way to do that is to extend the Composite class.

    From the documentation:

    A composite is a specialized widget that can contain another component (typically, a Panel) but behaves as if it were its contained widget. You can easily combine groups of existing widgets into a composite that is itself a reusable widget. Some of the UI components provided in GWT are composites: for example, the TabPanel (a composite of a TabBar and a DeckPanel) and the SuggestBox.
    Rather than create complex widgets by subclassing Panel or another Widget type, it’s better to create a composite because a composite usually wants to control which methods are publicly accessible without exposing those methods that it would inherit from its Panel superclass.

    There is a good example to get you started here:
